Hangers

Casing slip hangers

The hangers are used for hanging and sealing of the casings in casing heads and spools.

The hangers with primary seals operate at temperatures from -600C up to +1250C in working medium with content of H2S and CO2 up to 25% each.

The primary seals of slip hangers have been successfully hydrostatically tested at 15000 psi.

The hangers can bear the load of up to 5000 kN (500 000 kg).

The slips are nitrocemented h0.5…0.8mm and provide the reliable fixing of the casings.

There are four types of casing slip hangers.

Type I and type II are with manually energized primary seal.

The slip hanger, type I has simple design. It is used for the casings with the outside diameter tolerance up to +/- 2 mm.

For the casings with the outside diameter tolerance up to +/- 6mm the slip hangers type II and type III are used.

The slip hangers type II are made with one additional ring which is set against the groove in the body under the seal. The primary seal can be energized automatically under the casing weight.

Slip hangers type III and type IV have separate primary seal consisting of two metal rings and one elastomer seal providing the reliable sealing of the casing under the working pressure.

The hangers are energized automatically under the casing weight.

Type III slip hanger is widely used in the technology of oil and gas production in Northern Region of Russia at working pressures up to 10000psi.

Type IV slip hanger is used in the technology of oil production at working pressures up to 3000 psi.

type IV

Tubing hangers

We offer tubing hangers without control line, with control line, and with the thread for BPV.

The tubing hangers with elastomer seal are used for working pressures up to 10000psi, working temperatures from -60°C up to +125°C, working mediums with content of H2S and C02 up to 25% each. Maximum load on the hanger according to the tests -1300 kH (130 000kg).

The elastomer seal ring is energized under the casing weight and by means of stop screws if the weight is not enough for energizing the seal.
